Macbook Air Fan spinning for no reason

Hi everybody,


I have a strange issue with my Macbook Air 2017 13"


The fan starts getting noisy 3 or 4 times a day without any workload. If I look at the RPM with "Fanny", the value is wrong (shows like half the minimum RPM).


Strange thing: If I put some real work on the CPU ("yes> /dev/null & yes> /dev/null & yes> /dev/null & yes> /dev/null") the fan stops IMEDIATELY.


I tried ALL troubleshooting hints with no luck. In the end I returned the macbook to the vendor and received a new one as we thought it's an hardware issue --> New macbook, same problem.


The apple support is no help...


Is anybody struggling with similar issues?


Thanks

MACBOOK AIR (13-INCH, 2017), macOS High Sierra (10.13.5)
